Mexico–United States is the bilateral relationship between the United Mexican States and the United States of America, spanning diplomacy, trade, security, migration, and culture. The relationship evolved through wars such as the Mexican–American War, treaties such as the Treaty of Guadalupe Hidalgo, and recent agreements such as United States–Mexico–Canada Agreement. Shared geography includes a 3,145-kilometre border between Baja California and Texas, with major transborder pairs like Ciudad Juárez–El Paso, Tijuana–San Diego, and Nuevo Laredo–Laredo.

History

The international boundary extends from the Gulf of Mexico to the Pacific Ocean, crossing states such as Texas, New Mexico, Arizona, California on the U.S. side and Chihuahua, Sonora, Coahuila, Nuevo León, Tamaulipas, Baja California on the Mexican side. Key crossings include Bridge of the Americas (El Paso–Ciudad Juárez), San Ysidro Port of Entry, and the Brownsville & Matamoros International Bridge. The region contains ecosystems like the Sonoran Desert, Chihuahuan Desert, and the Rio Grande/Río Bravo del Norte riparian corridor, with transboundary conservation efforts involving International Boundary and Water Commission and initiatives linked to United Nations Environment Programme frameworks and regional groups such as Commission for Environmental Cooperation.

High-level diplomacy has been conducted through visits by leaders including Benito Juárez, Porfirio Díaz, Álvaro Obregón, Lázaro Cárdenas, Miguel Alemán Valdés, Luis Echeverría, Carlos Salinas de Gortari, Vicente Fox, Felipe Calderón, Enrique Peña Nieto, Andrés Manuel López Obrador, and U.S. presidents listed above. Bilateral mechanisms include the Ambassador of Mexico to the United States, the Ambassador of the United States to Mexico, and missions in Washington, D.C. and Mexico City. Negotiations have addressed disputes adjudicated by institutions such as the International Court of Justice on transboundary water and by the World Trade Organization on trade measures, while major diplomatic milestones include the Zapatista uprising's regional impacts and accords under North American Free Trade Agreement and its successor.

Economic integration intensified under North American Free Trade Agreement and its successor United States–Mexico–Canada Agreement, linking industries in Maquiladora zones, automotive clusters involving companies like General Motors, Ford Motor Company, Chrysler, and Mexican firms such as Cemex, Grupo Bimbo, and América Móvil. Trade corridors traverse ports including Port of Houston, Port of Los Angeles, Manzanillo (Colima), and Veracruz (port), with logistics via Union Pacific Railroad and Kansas City Southern de México. Energy cooperation involves Petróleos Mexicanos, ExxonMobil, Chevron Corporation, and recent reforms affecting state-owned enterprises and cross-border pipelines. Financial links include Banamex, BBVA Bancomer, JP Morgan Chase, and capital flows influenced by Federal Reserve System policy and Banco de México.

Populations are shaped by historic and modern migration: 19th-century movements after the Mexican–American War, the Porfiriato labor shifts, wartime Bracero Program, and contemporary migration driven by factors linked to Narcotraffic-related violence and economic differentials. Mexican-origin communities concentrate in California, Texas, Arizona, Illinois, and Nevada with cultural hubs in Los Angeles, Chicago, and Houston. Immigration policy instruments include Immigration and Nationality Act, Deferred Action for Childhood Arrivals, Secure Fence Act of 2006, Operation Streamline, and bilateral labor arrangements. Demographic institutions such as the United States Census Bureau and INEGI monitor cross-border population dynamics.

Security cooperation confronts transnational organized crime, Mexican drug cartels such as Sinaloa Cartel, Los Zetas, Gulf Cartel, and Juárez Cartel, with joint efforts under programs like Merida Initiative, Plan Colombia parallels, and collaboration between Federal Bureau of Investigation, Drug Enforcement Administration, Secretaría de Marina (Mexico), Secretaría de la Defensa Nacional (Mexico), and state police forces. Border enforcement uses U.S. Customs and Border Protection, U.S. Border Patrol, National Guard (United States), and Mexican federal agencies, while legal frameworks include the Extradition Treaty and mutual legal assistance via Interpol and bilateral agreements. Issues such as arm trafficking, money laundering, and human smuggling engage financial regulators like FinCEN and judicial bodies such as Supreme Court of the United States and Suprema Corte de Justicia de la Nación.

Cultural exchange spans artists, media, and cuisine with figures and institutions including Frida Kahlo, Diego Rivera, Octavio Paz, Carlos Fuentes, Gael García Bernal, Salma Hayek, Alejandro González Iñárritu, Luis Miguel, Selena, Los Tigres del Norte, Mariachi, and museums such as Museo Nacional de Antropología and Smithsonian Institution. Festivals like Cinco de Mayo celebrations, Día de los Muertos observances, and sporting rivalries in Major League Baseball, National Football League, and Liga MX illustrate social bonds. Educational and research ties involve universities such as University of California, San Diego, University of Texas at Austin, Universidad Nacional Autónoma de México, Tecnológico de Monterrey, and programs like exchange initiatives under Fulbright Program and binational centers.
